TECHNICAL LABORATORY & QUALITY CONTROL
At Global Silica Raw, consistency and high chemical stability are our core production metrics. Every single batch of our naturally micronized amorphous silica and pozzolanic minerals undergoes comprehensive testing in our state-of-the-art laboratory infrastructure.
We utilize advanced XRF (X-Ray Fluorescence) and XRD (X-Ray Diffraction) analysis to guarantee precise oxide distributions, while strict sieve and laser particle size analysis ensure exact micron consistency tailored to international industrial standards (such as ASTM C-618 and EN 196-5).

II. Physical & Mechanical Properties (Official Sieve & Geomechanical Data)
Our raw materials are structurally cataloged based on particle distribution, density, and compressive strength:
A) Particle Size & Micron Distributions (Sieve Testing)
- M-Sorb 3060 Series (Marine & Filtration Grade): Optimized between 300 – 600 Microns. Engineered for zero wind-drift and high-velocity oil absorption on sea surfaces.
- M-Sorb 5012 Series (Offshore & Industrial Grade): Optimized between 500 – 1200 Microns. Engineered for high-wave maritime spill response and heavy liquid filtration.
- Ultra-Fine Filler Series: 0 – 45 Microns (Naturally Micronized Powder Form). Engineered for high-adhesion construction chemicals and paint industries.
B) Compressive Strength & Density Parameters
- Premium White Silica (Çardak Matrix): Features a unique hollow sphere geometry providing a high vertical crushing resistance up to 50 Tons (12-22 MPa) despite its ultra-lightweight structural density.
- Industrial Welded Tuff (Çat/Ağaçören Matrix): High-density resources featuring an aggressive compressive strength of 25 – 35 MPa, highly recommended for sandblasting and abrasive finishing industries.
- Soft Puzzolanic Clay (Mucur Matrix): Low shear strength (7 – 12 MPa) allowing instant dust-free milling with zero added industrial processing energy.
III. Compliance & Certification Framework
Our materials are continuously tested to comply with global B2B trading frameworks:
- ASTM C-618 Class N Specification: For raw natural pozzolans used in high-performance green cements.
- EN 196-5 Pozzolanicity Test: Fully certified for active calcium hydroxide fixation in cement matrixes.
- Hydrophobic & Oleophilic Certification: Guaranteed water-repellent and hydrocarbon-selective absorption matrix for marine spill disaster response protocols.
